Did you know?
The difference between NO and NOT does not exist in the same way in Spanish: "no" in Spanish negates verbs, adjectives, and nouns equally. This is the main reason Spanish speakers produce "she is no ready", it is a perfect grammatical calque from Spanish. The words NO and NOT share the same Proto-Germanic root: "ne" (negation). Over time, NO specialized as a noun negator (negating things that exist) and NOT as a predicate negator (negating what is done or described). In Old English, they were written as "na" and "naht" respectively.
